secondary overflow ball mills

Home /Secondary Overflow Ball Mills Secondary Overflow Ball MillsWe are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment,millingequipment, mineral processing equipment and building materials equipment.

The cost of a ball mill conversion from overflow to grate discharge is ‘fairly’ affordable at $65,000for a13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber).

【Type】 according to the discharge type,overflow ball mill,grate discharge ball mill; according to the grinding conditions,wet milling, dry grinding; according to theball millmedia. 【 Wet grinding 】 gold, chrome, tin, coltan, tantalite, silica sand, lead, pebble, and the like mining application.

Grate-dischargeType. The grate-discharge type ofBall Millhas a grate at the outlet of the shell and causes less excessive grinding, compared to theoverflowtype. Therefore, generally, it is best suited to grind materials up to the particle sizes ranging from 60 to 100 mesh.

0.5 to 50 TPHIndustrial Ball Mills Industrial Ball Millsuse horizontal rotating cylinders that contain the grinding media and the particles to be broken. The mass moves up the wall of the cylinder as it rotates and falls back into the “toe” of the mill when the force of gravity exceeds friction and centrifugal forces.

The primary sump outlet stream is sent to the primary cyclone. Theoverflowfrom the primary cyclone goes to thesecondary sumpand the underflow is taken as a feed to theball mill. The slurry generated in thesecondary sumpis taken to another hydro-cyclone which is called assecondary cyclone. The underflow of thesecondary cycloneis recycled back to theball millfor grinding and the final product is theoverflow…

Even though production was dramatically improved, the product size of thesecondary ballmilling was reduced and recovery increased. The results in SAG-Millline 2 are even more dramatic. Because of segregation on the coarse feed stockpile, SAG-mill2 receives a higher percentage of coarse material.

Overload inoverflow ball millsis due to the approach to a critical axial flow velocity for pulp of 0.072 m/s. 2) While so far important only with 5.0 and 5.5 m diametermills, it should be found with smallermillsin combinations of very high circulating loads, excessive L/D ratios, very soft ores or coarse grinds. 3.
